Question Parameters:

a 0.50 M solution of HOCl at 25℃. pKa = 7.46 at 25â„

Generally, the equation for the Chemical Reaction  is mathematically given as

HOCl=H30+ClO

Therefore

ka=\frac{H3O(ClO)}{HOCl}

Ka=10^{-7.46}

x.x/0.5-x=10^{-7.46}

x=1.317*10^{-4}

In conclusion

a)

Answer:

the correct answer is number 7

Answer:

Ionic, atomic, and molecular particles (ions, atoms, and molecules) As a result of strong inter-particle forces, the particles are only able to vibrate rather than move freely. This results in solids having a stable, distinct shape as well as a distinct volume. Solids can only be broken or cut by an outside force.

Nuclear and Biomass energy are the type of energies that differs from each other in producing carbon dioxide. Thus, option A is accurate.  

Nuclear energy is nonrenewable energy that concerns nuclear reactions to produce electricity. It includes the nuclear fission of the atoms to release energy.

Biomass energy is a renewable source of energy that utilizes and employs living and nonliving biomaterials to generate energy in the form of fuel and electricity. It also produces carbon dioxide as a by-product.

Therefore, option A. the release of carbon dioxide differs nuclear energy from biomass energy.

As Per Given Information

Given mass of H₂O₂ ( Hydrogen Peroxide) 4.0 gm

We've been asked to find the number of moles in Hydrogen Peroxide .

First we calculate molecular mass of Hydrogen Peroxide .

Molecular mass of H₂O₂ = 1×2 + 16 × 2

Molecular mass of H₂O₂ = 2 + 32

Molecular mass of H₂O₂ = 34 gm

Now find the number of moles in given hydrogen peroxide .

[tex] \diamond{\boxed{\blue{\bf{Number \: of \: moles \: = \frac{Given \: mass}{Molecular \: mass} }}}} [/tex]

Put the given value we obtain

[tex] \sf \twoheadrightarrow \: Number \: of \: moles \: = \frac{4}{34} \\ \\ \sf \twoheadrightarrow \: Number \: of \: moles \: =0.117[/tex]

So, the number of moles is 0.117 .

Answer:

Plates on Earth's surface shift as a result of strong heat in the Earth's core, which causes molten rock in the mantle layer to move. It flows in a pattern known as a convection cell, which formed as heated material rises, cools, and then sinks. As the cooled material lowers, it heats up and rises again.

Explanation:

The woman that has 7.9 * 10-3 mol of hemoglobin in her blood has 509.20 grams of hemoglobin in her blood.

The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass. That is;

mass = no. of moles × molar mass

According to this question, a woman has 7.9 × 10-³ mol of hemoglobin in her blood. The mass of hemoglobin in her blood is as follows:

mass = 7.9 × 10-³ × 64,456 g/mol

mass = 509.2grams.

Therefore, the woman that has 7.9 * 10-3 mol of hemoglobin in her blood has 509.20 grams of hemoglobin in her blood.

In an ecosystem with an increase in population of young women there can be an increase in the number of births.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
